Frost formation is a normal phase transition phenomenon in cold climates, while it usually brings certain troubles to human lives and production. Therefore, of great significance develop frost resistant materials key technologies. Here, salt-philic superhydrophobic surface designed on PDMS substrate by femtosecond laser direct writing technology combination with salt–ethanol–water mixtures droplet treatment. The laser-treated embedded salt (LTP-S) exhibits superhydrophobicity, which alone property that can resist the enables self-cleaning effect. Meanwhile, coating further enhances resistance reducing freezing point temperature. LTP-S revealed perform well frosting-defrosting cycles, washing resistance, chemical corrosion heating long-term air exposure tests as highly efficient stable anti-frosting surface. This work demonstrates facile strategy fabricate for anti-frosting.

Adaptable, Dynamic, and Superhydrophobic Standing‐Fiber Surface with Muti‐Level Energy Barrier for Anti‐Icing

Advanced Functional Materials, Год журнала: 2025, Номер unknown

Опубликована: Янв. 12, 2025

Abstract Passive deicing technologies achieved by dynamic superhydrophobic surfaces and slippery substances contribute to widely used anti‐icing. However, the constant status of microstructures cannot cater changing environment, meanwhile, energy barrier needs be improved. Here, a standing‐fiber surface with three‐level is fabricated electrical flocking technology, which directly utilizes wind field assist The has low ice adhesion 2.7 kPa, high water contact angle 171.1°, long icing delay time 859 s under −30 °C. superhydrophobicity contributes excellent repellency droplet retracting bouncing distance 3.53 3.75 mm. In at 9 ms −1 , inclined theoretically accelerates motion 1.5 times compared lying‐fiber surface. difference in thermal conductivity between front back sides makes it an ideal candidate for designing anti‐icing, deicing, insulation clothes.

Hyperbranched Vanillin‐Based Composite Coating: Achieve Efficient Icephobicity in High Humidity and Dynamic Environments

Advanced Functional Materials, Год журнала: 2024, Номер unknown

Опубликована: Сен. 30, 2024

Abstract Despite tremendous advancements in icephobic coating technology, efficacy frequently declines or completely disappears low temperatures, high humidity, and dynamic environments. Here, a hyperbranched vanillin‐based composite with efficient properties (HVIC) is prepared by combining phosphazene compounds oil‐stored SiO 2 through imine bonds‐ HVIC exhibits excellent hydrophobicity, water sliding angle of 9°. This coating's exceptional slippery performance imparts outstanding non‐adhesive, self‐cleaning characteristics, deicing (τ ice : 8.2 kPa). It noteworthy that performs anti‐icing anti‐frosting low‐temperature humidity Compared superhydrophobic coatings (SHC), the icing delay time 9.1 times SHC, frosting extended roughly 300%. Most importantly, HVIC‐treated propeller experienced two ice‐shedding events during 200s test, while SHC lost its performance. can ensure normal operation equipment reducing energy consumption. The also significant UV shielding, antibacterial, flame retardant, self‐healing, recyclability properties. regarded as having potential for application due to easy scalable approach.

Ultrahigh Transparent Safety Film for Spectrally Selective Photo/Electrothermal Conversion via Surface-Enhanced Plasma Resonance Dynamics

Nano Letters, Год журнала: 2024, Номер unknown

Опубликована: Сен. 12, 2024

Traditional deicing methods are increasingly insufficient for modern technologies like 5G infrastructure, photovoltaic systems, nearspace aerocraft, and terrestrial observatories. To address the challenge of combining anti-icing efficiency with operational performance, an innovative, spectrally selective, photo/electrothermic, ice-phobic film was prepared through a cost-effective mist deposition method. By manipulating diameter ratio density nanowires, local free electrons within this is controlled to precisely dictate position intensity surface plasmon resonance achieve selective photo/electrothermal conversion. Additionally, synthesized hydrophobic N-Boroxine-PDMS/SiO
